Excellent series of images.
#1 looks a bit dark on my monitor, but you have kept very good facial detail, that's hard to do, well done.
#2 Very well done, pity it wasn't on a frontal shot though
Very sharp shot, again, not easy to do with HIF
#3 It's a nice shot, but appears oversaturated to me, and soft (in the eyes), pity.
#4 As a crop of #3, the softness in the eyes is more apparent, pity 
#5 Excellent shot, nice exposure, done well avoiding highlights. Sharp as well. My only (slight) criticism is that perhaps it's a bit too tight of a crop...other than that, very nice. I would have liked to have seen more free space on the right hand side (if possible).
#6 My favourite shot, again very nice exposure and sharpness, and composition really works for me in this shot. Lovely.
#7 Same comments as #3.
